Best practice to run only one sharepoint.files
Hi Guys,
I want to have one datasource from SharePoint.Files (Csv tables) and based on this build seperated queries.
What is the best practice ?
I should build CSV tables in a source like add column here with Csv.Document ?:
and from query just filter specific row and expand table column?
Or i should create a table from binary for each seperated query?
I want to avoid refreshing in the loop SharePoint source a lot of times...
Best,
Jacek
correct-ish. There is no guarantee for that though. Chris Webb's BI Blog: Why Does Power BI Query My Data Source More Than Once?

pretty much . Table.AddColumn with a Csv.Document ingestion of the [Content] value. You need to specify the encoding and the quoting. Then you can drop the [Content] column and expand the newly created column for an automatic append.
Writing a blog entry on this topic at the moment.
Ok if i use Table.AddColumn with a Csv.Document and get all tables in SharePoint source and after that I will create Query1, and in this query i will filter all sharepoint query for specific query, if power query will rerun twice? If it will Refresh all sharepoint files query and after refresh them again it will refresh for filtering specific table within seperate query?
AllSharePointQueries with Add.TableColumn Csv table --> Specific table filtered within seperate query -> if AllSharePointQueries will be refreshed twice?
